Would somebody please explain to me what the two Galactic Journey posts, one by John Boston and one by Gideon Marcus, are? I am guessing that these (including the comments) were actually written back in the 1960's, probably from fanzines. Am I correct?

The conceit of the Galactic Journey blog is that it is being created 55 years ago, that the blog and its writers are in 1962. Everything written in the blog is pretty much new, but is pretending to be new then. Hello Yesterday's Today.
